DWR3基于Spring MVC配置Controller的方法

DWR3 可以使用Spring MVC来进行url映射，配置如下：

web.xml

<servlet>
<servlet-name>dwr</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dwr</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
<servlet>

需要一个dwr-servlet.xml的文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr"
xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.directwebremoting.org/schema/spring-dwr http://www.directwebremoting.org/schema/spring-dwr-3.0.xsd">


<!-- 将util.js和engine.js映射到下面的dwrController -->
<dwr:url-mapping />

<!-- debug开启 -->
<dwr:controller id="dwrController" debug="true" >
<!-- 如果有反向Ajax调用 -->
<dwr:config-param name="activeReverseAjaxEnabled" value="true" />
</dwr:controller>

</beans>

然后在Spring 的主配置加入如下配置，就可以使用DWR标注了

<!-- 启用 annotation 配置模式 -->
<dwr:configuration >
<dwr:convert type="bean" class="org.feifei.*"></dwr:convert>
</dwr:configuration>

<!-- Spring容器中检查拥有@RemoteProxy 和 @RemoteMethod注解的类 -->
<dwr:annotation-config>
</dwr:annotation-config>
